WILLIAM THOMAS WOOD, OF NASHVILLE, TENNESSEE.

VAPOR-LAMP.

To all whom fit may concern.'

Be it known that I, WILLIAM THOMAS WOOD, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented a new and useful Vapor-Lamp, of which the follow ing is a speciiication.

This invention relates to that part of lamps wherein liquid fuel is converted into vapor, which in turn is mixed with air and afterwards burned to cause the incandescence of a mantle.

The principal object in the present invention is to produce a novel structure, which is not only very efficient in operation, but is exceedingly simple in construction, so that it can be manufactured at small cost.

The referred embodiment of the invention is illustrated in the accompanying draw* ings, wherein Figure 1 is a vertical sectional view through the lamp. Fig. 2 is a front elevation thereof. Fig. 3 is a sectional view on the line 3 3 of Fig. 1. Fig. 4 is a sectional view on an enlarged scale on the line 4-4 of Fig. 3.

Similar reference numerals designate corresponding parts in all the figures of the drawing.

In the form of construction illustrated, a one-piece su port is em loyed, consisting of a vertically disposed va ve casing 5 from an intermediate portion of which extends a hori zontally disposed starting cup 6, having on diametrically opposite sides offset ears 7. A fuel conducting channel or conduitextends through the interior of the valve casing, and is supplied from any suitable source through the medium of a pipe 9. The channel 8 includes a vertically disposed portion 10 surrounding a valve seat 11 and co erating with the seat is a needle valve 12 t 1eaded into the casing through its lower end and preferably surrounded by a suitable stuffing Secured to the ears 7 of the starting cup is a mixing and burner element comprising an upstanding mixing chamber 14 and spaced upstanding burners 15, communicating at their lower ends with the lower end of the chamber, as shown at 16. The burners 15 have perforate ca s 17 and are disposed on opposite sides of t e mixing chamber and between the same and the supply pipe 9. The mixing chamber is supplied with air through conduits 18, communicating with the upper end of the said chamber and extending exte- Specification of Letters Patent.

riorly and downwardly on opposite sides of the chamber, their lower inlet ends being open, as shown at 19, and being disposed below the horizontal plane of the upper ends of the burners 15. These conduits constitute what may be termed a dome or hood that extends on opposite sides' of and over the upper open end of the tube 14, as shown in Fig. 3.

A vaporizing tube connects the upper end of the valve casing 5 and the upper end of the mixing chamber. One end of the said tube is threaded, as shown at 20, into the u per end of the casing 5 and is surrounded y a stuffing box 21. From this end, the tube extends vertically, as shown at 22, and has its upper portion arranged in overhanging relation, as illustrated at 23. From the overhanging portion 23 to the mixing chamber, the tube is formed with a serpentine curve that produces a series of opposite elon ated vertically disposed loops 24 and 25, the oops 24 extending at an inclination downwardly toward the vertical portion 20, the outstanding loops 25 extending upwardly. The various loops and the vertical portions 22 are arranged in substantially the samel vertical plane, which plane passes between the burners 15 and bisects the mixing chamber 14. This it is thought will be clear by reference to Fig. 2.

The discharge end 26 of the vaporizing tube is located directly over the upper end of the mixing chamber to which it is fastened by a clamp bracket 27. The said end terminates above the chamber, the latter, or hood, having an inlet orifice 28 in line therewith. A tip 29 is slidably iitted in the discharge end of the tube and has its inner portion provided with a downwardly tapered opening 30, terminating in an orifice 3 1 that is in register with the orifice 28. A stem 32 having its lower end secured to a depending lug 33 on the mixing chamber has its upper end connected to the tip 29 to hold the same in place. The lower portion 34 of the stem 32 is looped in order to permita yielding movement thereof.

In the operation of the device a preliminary heating of the burner is ed'ected by means of suitable material placed in the cup 6, as is well known to those skilled in the art. The passage of fuel supplied through the pipe 9 is controlled by the valve 12, and that which passes into the v'aporizing` tube will successively enter the various loops. The lower ends of the inwardly extending loops constitute traps in which the liquid will be maintained until vaporized, and their particular disposition is important. By having them one below the other, each is subjected to the fullest degree of heat from both of the opposite burners, and one will not interfere with the passage of the heat to the other. Moreover by the arrangement as disclosed, the liquid iirst enters the uppermost loop or trap, and if any passes the saine, it will gravitate to the next and so on through the others. These traps are located different distances above the burners and are therefore subjected to different degrees of heat, and as a result, the complete vaporization of the liquid is insured. Vapor passing through the tip 29 will be injected into the mixing chamber l5. Here it Will ntermingle with the air supplied through the conduits 18, and the mixture will pass through the burners 15. It will be evident that the structure is very simple, so that it can be readily andcheaply manufactured, and it is furthermore entirely effective, insuring the complete vaporization of fuel before the same reaches the mixing chamber.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention will ybe apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is i l.
